Abstract: Aspects described herein relate to on-demand soft acknowledgement (ACK)/negative acknowledgement (NACK) in radio access and other wireless networks, such as fifth generation new radio (5G NR), 3GPP Long Term Evolution (LTE), 3GPP LTE-Advanced (LTE-A), Wi-Fi, and the like. In an example, the aspects may include receiving, from a network entity, a request to enable soft ACK/NACK feedback; enabling the soft ACK/NACK feedback based on the request, where the soft ACK/NACK feedback comprises at least a link quality metric per diversity branch; and transmitting, to the network entity, the soft ACK/NACK feedback based on a determination to enable the soft ACK/NACK feedback.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a communication device may receive control signaling (e.g., a broadcasted control signal) from another communication device. The control signaling may indicate beam information for one or more beams of a set of beams. The one or more beams may correspond to the serving cell or one or more neighboring cells. The beam information may include one or more metrics associated with each of the one or more beams. As such, the communication device may determine that a metric associated with each of the one or more beams satisfies a threshold, select the beam, and communicate using the selected beam. In some other examples, the beam-specific information may include beam measurement offsets for one or more beams. In such examples, the communication device may select a beam based on the beam measurement offsets and perform communications using the selected beam.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication includes shifting, based on a partial overlap between a scheduled downlink transmission occasion and a scheduled uplink transmission occasion that each include a first and second repetition, a first repetition boundary of one transmission occasion of the downlink transmission occasion or the uplink transmission occasion, and performing full duplex communication with repetition based on the shifted first repetition boundary. In some implementations, shifting includes shifting an entirety of the one transmission occasion. In some implementations, shifting the first repetition boundary changes a number of consecutive symbols included in the first repetition of the one transmission occasion. In some implementation, the method includes adding a third repetition boundary to the one transmission occasion. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit signaling to a first network entity indicating a location of the UE and a measured reference signal receive power (RSRP). The UE may receive an indication of a time division duplex (TDD) configuration and a slot format indicator (SFI) for communications between the UE and the first network entity based on the RSRP or location. In some cases, the first network entity may receive signaling indicating a set of resource configurations from a second network entity. The first network entity may select a resource configuration (e.g., for communications with the UE) from the set based on a measured RSRP indicated by the UE or a location of the UE. The UE and the base station (e.g., the wireless device and the first network entity) may communicate according to the indicated or selected resource configurations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a minimum time gap for a set of uplink transmissions in a set of timing advance groups; and schedule a first uplink transmission, of the set of uplink transmissions, in a first timing advance group, of the set of timing advance groups, and a second uplink transmission, of the set of uplink transmissions, in a second timing advance group, of the set of timing advance groups, with at least the minimum time gap between the first uplink transmission and the second uplink transmission. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to configuring, restricting, and/or setting bandwidth part (BWP) or frequency locations for switching from source to target cells in a Layer 1 (L1)/Layer 2 (L2)-Centric Inter-Cell Mobility communication systems. Switching may be allowed for either same, overlapping, or non-overlapping BWPs within an intra-frequency bandwidth shared by the source and target cells.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a first connection with a source base station. The UE may determine that a handover procedure is being performed for establishing a second connection with a target base station. The UE may monitor, during a monitoring period instantiated at a physical layer of a protocol stack of the UE, for a control signal acknowledging success of the handover procedure from a target base station. The UE may transmit, based at least in part on a result of the monitoring during the monitoring period, a physical layer signal or a medium access control layer signal to the source base station indicating that the handover procedure was unsuccessful based at least in part on a failure to successfully receive and decode the control signal.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a random access occasion may overlap in time with a synchronization signal block resource, where the random access occasion and the synchronization signal block resource have a same index. In some such examples, a base station may transmit, to a user equipment (UE), an indicator of a mapping of the random access occasion to an uplink beam that is associated with a synchronization signal block resource with a different index than the random access occasion. The UE may transmit, to the base station, a random access preamble over the random access occasion using the uplink beam.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a random access channel (RACH) occasion (RO) based on one or more channel quality thresholds, such as reference signal received power (RSRP) thresholds. A base station may determine a set of RO types for receiving RACH transmissions. The base station may determine a channel quality threshold for each RO type. The base station may broadcast a configuration indicating the RO types and the associated channel quality thresholds. The UE may receive the configuration and measure a channel quality between the UE and the base station. Based on the measured channel quality, the UE may determine which RO types are available based on the indicated channel quality thresholds, and select an RO for transmitting a RACH preamble to establish a connection with the base station based on the available RO types.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit reference signals via a first antenna array of the first wireless device. The first wireless device may perform, according to a reporting configuration for self-interference at the first wireless device, a set of measurements on the reference signals received at a second antenna array of the first wireless device. The first wireless device may determine a priority associated with transmission of measurement reports associated with self-interference at the first wireless device. The first wireless device may then transmit, to a second wireless device and according to the reporting configuration, a measurement report including an indication of self-interference for full-duplex communications at the first wireless device that is based on performing the set of measurements on the reference signals, where the measurement report is transmitted in accordance with the determined priority.
